Trailer: Joss Whedon's New Horror Flick 'Cabin in the Woods' With Chris Hemsworth

Between the work he's done on "Buffy the Vampire Slayer," "Firefly," "Angel," "Dollhouse" and the upcoming movie "Avengers," Joss Whedon is one of the most in demand writers in Hollywood.

The trailer for his latest writing effort, "The Cabin in the Woods" was just released, and many of the same faces from his earlier projects are on board to experience some unspeakable horror.

Amy Acker from “Dollhouse” and “Angel”, Tom Lenk from “Buffy the Vampire Slayer” and “Angel” and Fran Kranz  of “Dollhouse” all take part in the melee, and the film stars Richard Jenkins, Bradley Whitford and (weirdly) "Thor" star Chris Hemsworth.

The film is "Lost" producer and "Buffy the Vampire Slayer" writer Drew Goddard's directorial debut.

"Cabin in the Woods" hits screens April 13, 2012.
